The address listed for Marcelina is apparently just an office. No one was there when I arrived, and the hotel did not contact me in advance requesting a specific time of arrival or explaining the situation. After about 20 minutes, a man showed up and escorted me to the actual location, a couple of blocks away on Via Varese. (The main name for the establishment is When In Rome.) I was given a large room with 2 sofabeds in addition to a double bed. 5 people could have slept there—but not comfortably, because it was a sauna. Even after the evening came, Rome cooled off, and I opened the windows wide, this room remained hot all night. The air conditioner was feeble and useless. The one chair was broken and unusable. Lamps lacked lightbulbs. In the morning, no one was at the desk by 8:30, even though they supposedly open at 8. The staff wasn't unpleasant, but apparently they don't know how to create a comfortable experience. Add shared bathrooms, and you have poor lodging at a relatively high price.
